7 To all whom it may concern Be it known that we, LUKE J. FAIRBANKS andJOHN R. KELLY, both citizens of the I United States, residing atLos Anles, in

the countyof Los Angeles and tate of California, have jointly inventednew and useful Improvements in Sample-Dispensers, ofwhich the followingis a. specification.

This invention relates to'sample dispensers, and has for its object toprovide a sample dispenser suitable for use of grocery salesmen,canvassers and the like, for display and dispensing of wares such assemiliquids, pick es, the contents of canned goods, and in fact, allgoods of such nature as would otherwise be diflicult of display a andsampling. v I

A further object of the invention is to provide an improved sealingmeans associated with the closure and'cooperating with aertain portionsof the receptacle whereby such closure may be readily and quickly placedin position and removed and. when assembled will render the receptaclefluidhl 1 i he invention has for a further object to provide an improveddispenser of the general character stated in which utility is comandservices, which may be readily carried in apocket, and which will be'super1or 111 point of relative simplicity arid mexpensiveness ofconstruction and organizatlon, combined with efi'ectiveness inoperation, and use, and durability, andv compactness in form.

With the above and other objects in view, the invention consists in thenovel provision, formation, association and relative arrangement andinterrelation of parts, members and features, all as hereinafterdescribed shown in the drawing and finally pointed out in claims.

In the drawing:

Figure 1 is'an isometric view of the improved dispenser showing theparts in assembled position;

Fi 2 is a cross sectional side elevation, certam parts being brokenaway, of thedis- P615881, and taken on the line w w Fig. 3; an

ing, A designates a. container, B a closure means for said container, Ca sealing means,

and D means for securing the closure means.

B to the container A.

. The container A comprises a bottom member 1, sides and 3 and ends 4and 5; said contalner being open at the top; the side and end portions2, 3, 4 and 5, respectively have adjacent their upper edges a downwardlyand outwardly curved rim 6.

The closure means B comprises a plate having practlcally a flat topsurface 7, with certain portions such as 8 curving down-, wardlycompletely around the plate. The plate is likewise provided with anupwardly extending flange 9 which in turn is provided 5 with a rim whichextends first laterally as at 10 and then 1s downwardly and returnedlycurved as at The closure-means B like- -w1se 1s provlded with a centralannular convex or outside or upstruck beaded portion 12 and a centralorifice or perforation 13 is'located intermediate the annular convexbeaded portion.

The sealing means C prefera-bl includes an endless rubber gasket or banmade so that it resembles in cross section, as shown in Figs. 2 and 3, awedge having angularl disposed faces as 14, 15 and 16, one of whicfaces, as 15, engages a surface of the flange 9 while another of itsfaces, as 16, engages the laterally extending portion 10 of the rim,while the downwardly and returnedly curved portion 11, of the rim,engages a small portion of the face 14. Thus the wedge-shaped sealinggasketv or band C is held in close relation to the rim part and theflange part of the closure means B, as illus-' trated in the fi res.

The means for securing the closure member B to the container A comprisesa cross bar 17 having downwardly and u wardly bent end portions as shownat 1 a and 17 The upwardly bent portions as 18 and 19 en age the surfaceof the down.- wardly 31K? outwardly curved rim 6 of the container A.There is an enlar ed part 20 central of the cross bar 17 and whichenlarged part is provided with a threaded perforation 21, extendingtherethrough. A threaded bolt 22 passes through and turns upon thethreaded portion of the perforation 21.- One end of said bolt isprovided inner peripheral surface adjacent the rim with an'ann'ularflanged cap as at 23, having an enveloping gasket 23 thereon,while the opposite end is provided with an integrally formed head 24. vI

The operation is as follows: When the closure means B is in positionupon the container -A as shown in the figures, the cross bar 17 isplaced in position so thatits downwardly and upwardly bent portionsvcontact with the undersurface of the rim of the container and theannular flange cap 23 will rest between the central annular convexbeaded portion of the closure means B.

As Wlll be observed by referrin to Figs. 2 and 3, the angularly disposedace 14 of the sealing means C will bear'against the 6 of the containerA. If now the bolt head 24 is revolved in such a manner that it tends tomove downwardly, adownward pressure will be exerted a ainst the closuremeans B while an upwar pressure will be exerted on the container A.

Because the sealing means is provided with angularly disposed faces,when the closure B isin position upon the container A. as illustrated inthe figures, it will be observed that any contents, especially if theybe fluids, that may be contained within the container A, will, in caseof shaking, only contact with the interior surface of the side walls andend-walls of the container, and

the inner surface of the closure means B as far as the flanged portionof said closure means. The angularly disposed face 14 of the sealingmeans prevents any liquid from splashing or coming in contact with theouter peripheral surface of the rim 6, and it is a main feature of thisinvention that the face 14 of the sealing means 0 should be so disposedthat a pressure exerted upon the closure means B will only increase thewedge-like gripping action exerted between the sealing means and theinner surface ofthe container adjacent the rim. It is com-' monly knownthat if a fluid is permitted to moisten the rim beneath a rubber gasketand the closure is then sealed over said means that the fluid contentswithin the container may leak because of said moisture between thesealing means and the rim, but with the articular construction abovedescribed this eaking is of course obviated.

Sometimes it is diflicult to remove a closure after it has once beensealed upon its corresponding container member, but in this inventionafter releasing the cross bar 17 the perforation or orifice containedwithin the closure means D will allow theatmospheric pressure upon theinterior of the container A to equalize with the atmospheric pressure onthe exterior of the container, permitting the cover to be removed.providing the rubber gasket or sealing means "C is not stuck to thecontainer A. If this should happen, particularly if the cover weresealed upon the container when the same'ls warm, the sealing means Cwould tend to bind or stick very closely to the rim edge 6. In order torelease the cover, the

. securing means D is provided with an extension 17 which is integrallyformed with the part-17. i This extension 17, allows the cover B to bepried from the container A,

and the means D twisted.

It is obvious that many changesand modifications may be made inpractising the above inventionas shown in the drawings, described in thespecification and pointed outin claims, but in no case departing fromthe true spirit thereof Having thus disclosed our invention, we claimand, desire to secure by Letters Patent:
